利用Swashbuckle生成Web API Help Pages
本文将通过Swagger的.NET Core的实现封装工具Swashbuckle来生成上一篇-《创建ASP.NET Core Web API》的帮助文档。
Swashbuckle简介
Swashbuckle有两个核心组件：
- Swashbuckle.SwaggerGen: 提供生成描述对象，方法，返回类型等JSON Swagger文档的功能。
- Swashbuckle.SwaggerUI: 一个Swagger UI工具的嵌入式版本，可以使用上面的文档来创建可定制化的Web API的功能描述，包含内置的公共方法的测试工具。
在middleware中添加并配置Swagger
首先,要将Swashbuckle添加到项目中的project.json：
"Swashbuckle": "6.0.0-beta902"然后在Configure方法中添加SwaggerGen到services集合中，接着在ConfigureServices方法中，允许中间件(middleware)为生成的JSON文档和SwaggerUI提供服务。
执行dotnet run命令，并导航到http://localhost:5000/swagger/v1/swagger.json 查看描述终结点的文档。

}该文档用来驱动Swagger UI，可以导航http://localhost:5000/swagger/ui来查看Swagger UI。
在UserController里面的每个方法都可以在该页面上通过点击"Try it out!"进行测试。
定制&扩展
API描述信息
ConfigureSwaggerGen方法可以用来添加作者、版权、描述等信息。
services.ConfigureSwaggerGen(options =>
{
options.SingleApiVersion(new Info
{
Version = "v1",
Title = "User Web API",
Description = "ASP.NET Core Web API",
TermsOfService = "None",
Contact = new Contact { Name = "Charlie Chu", Email = "[email protected]", Url = "http://zhuchenglin.me/" },
License = new License { Name = "The MIT License", Url = "http://zhuchenglin.me/" }
});
});XML注释
通过在project.json添加“xmlDoc”: true来启用XML注释。
ApplicationBasePath获取该应用的根路径，它必须为XML注释设置一个完整的路径，生成的XML注释名称基于你的应用程序的名称。
注意这个界面是通过之前生成的JSON文件来驱动的，所有的这些API描述信息和XML注释都会写入到这个文件中。
